Application October 5, 1934, SeralNo. 747,051 1 Claim. (Cl. 12S-306)This invention relates to a castration clamp, or extends atsubstantially right angles to the and has for its principal object theproduction of shank portion I9 of the lever I 6 and th1s operatjaw and amovable jaw which movable jaw is its upper edge for the purposehereinafter de-v adapted to be forced into clamping engagement scribed.The shank portion I9 of the lever I6 with the stationary jaw. carries alink 2I which link is adapted to engage A further object of thisinvention is the producthe rack 22 carried by the shank I I for thepurtion of a castration clamp which is so constructed pose of holdingthe lever I6 in a closed position as to effectively crush the cord ortesticle sack such as is shown in Figure 1. in such a manner as toprevent the breaking of An adjustable jaw 23 having a shank portion theskin or the drawing of blood. 24 is slidably mounted between theV platesI3 and A still further object of this invention is the the adjustablejaw 23 is provided with a rounded provision of a simple and efcientmeans for tiltupper face 25 similar to the rounded lower face ing theadjustable jaw in such a manner as to I2 of the jaw I0 to provide asmooth contacting prevent the sack or cord from moving outwardlyClamping face thereby avoiding presentation of A still further object ofthis invention is the ated upon. The shank portion 24 of theadjustproduction of a simple and ecient mounting for able jaw 23 isprovided with an arc-shaped lon-A 0 the adjustable jaw of the clampwhereby the adgitlldl'nally @Xtendng S1017 26 thlOllgh Which S1017justable jaw will be tilted with respect to the staextends a guiding pinor bolt 2'I carried by the With these and other objects in view this in-A second guiding slot 29 is formed in the shank vention consists incertain combinations and con- 24 below the arc-shaped slot 26.

The stationary jaw I0 extends at substanstraddling the armsI5, as shown in the drawtially right angles to the shank I I and isprovided ing. with a rounded lower face I2 to provide a smooth 'I'heoperation of the device is as follows:- contacting face in order toavoid presentation The cord or testicle sack is placed between the ofany sharp or cutting edges. 'Ihe shank II jaws I 0 and 23, and bycarefully considering Figcarries a pair of guiding plates I3 whichplates ure 3, it wlll be seen that the upper face 25 of are securelyheld against the faces of the shank the jaw 23 is slightly tilted tofrestrict the open- II by means of suitable rivets I4. Each plate I3 ingbetween the outer ends of the jaw I0 and jaw is provided near its lowerend with a. projecting 23 when the jaws are in an open position This armI5 between the outer ends of which arms I5 will tend to prevent the cordor sack from slipping outer end II pivotally mounted upon the supormovable jaw 23 is moved to a closed position. porting pin or bolt I8.This bolt or pin I8 is This tilting position of the jaw 25 isaccomplished carried by the outer ends of the arms I5. The by theposition 0f the pin 23 and the Din 27 withouter end I'I of the operatinglever I6 is offset in the respective slots 26 and 29. When these pins 2,Y s are in the upper ends of the slots 26 and 29, the shank 24 will beinclined, as shown in Figure 3, 23 is moved toward the jaw I0 the pin 3|by sliding 1n the inclined slot 29 will cause the shank 24 to movetoward the shank I I and to a substantially parallel position and thearcshaped slot 26 by riding over the pin 21 will also assist in movingthe shank 24 to a parallel position with respect to the shank I I. Theshank 24 is moved longitudinally or to a closed position'with respect tothe jawY I0 by swinging toward the shank I I thereby causing the camface 20 to engage the lower end of the shank 24 and push the shank 24longitudinally between the plates I3 to a clamping or closed position,such as is shown in Figure 1. The lever I6 may be held in this clampedposition through the medium of the link 2| engaging the rack 22. When itis desired to move the adjustable jaw 23 to an open position, the leverI6 may be swung to the position shown in Figure 3 and the coil spring 33will immediately pull the shank 24 downwardly to an open position andaway from the inner face of the shank II, such as is shown in Figure 3,causing the shank 24 to assume an inclined position, the lower end ofthe shank 24 being at all times in frictional engagement with the camface 2l) through the medium of the coil spring 33.

It should be understood that certain detail changes inthe mechanicalconstruction, combination and arrangement of parts may be emthe lever I6ployed without departing from the spirit of the invention so long assuch changes fall within the scope of the appended claim.

Having described the invention, what is claimed as new isz- A clamp ofthe class described comprising a stationary jaw, a shank supporting thestationary jaw, plates carried bythe stationary jaw and extendinglaterally thereof, a movable jaw having a shank slidably mounted betweensaid plates, lever means engaging said movable jaw for moving saidmovable jaw in one direction longitudinally of the plates, spring meansfor automatically drawing the movable jaw to an open position whenpressure is released from said lever means, af pin carried by saidplates, an inclined guiding slot formed in said shank of said movablejaw, said slot being inclined toward the inner face of the shank fromits bottom toward the top thereof whereby said shank o said adjustablejaw will be inclined outwardly at its bottom when said shank is in itslower position, and whereby said shank of said adjustable jaw willextend substantially parallel to` the shank of the stationary jaw whenthe stationary jaw is in a closed position, a longitudinally extendingarcshaped slot. formed in the shank oi the adjustable jaw, and a pincarried by the plates extending through said arc-shapedslot.
